h01ger and lynxis gave a talk called "From Reproducible Debian builds to
Reproducible OpenWrt, LEDE" (video, slides) at the OpenWrt Summit
2016 held in Berlin, together with ELCE,
held by the Linux Foundation.

A discussion on debian-devel@ resulted in a
nice quotable
comment
from Paul Wise: "(Reproducible) builds from source (with continuous
rechecking) is the only way to have enough confidence that a Debian user has
the freedoms promised to them by the Debian social contract."

Documentation update
After discussions with HW42, Steven Chamberlain, Vagrant Cascadian, Daniel
Shahaf, Christopher Berg, Daniel Kahn Gillmor and others, Ximin Luo has started
writing up more concrete and detailed design plans for
setting SOURCE_ROOT_DIR for reproducible debugging symbols,
buildinfo security semantics
and buildinfo security infrastructure.

Dmitry Shachnev noted that our patch for #831779 has been temporarily
rejected by docutils upstream; we
